  • Patent number: 12199787
    Abstract: [Object] To improve the reliability by using an acknowledgement response while using radio resources efficiently in multicast transmission over wireless transmission. [Solution] A plurality of wireless communication devices included in a multicast group, when receiving a data frame, transmit simultaneously an acknowledgement response of multicast using spatial multiplexing in response to an acknowledgement request from a transmission source. On the other hand, a wireless communication device of the transmission source decomposes the acknowledgement responses simultaneously received into the original individual acknowledgement responses and restores them using signal processing based on information on a channel with each wireless communication device of a transmission destination.
